At 17.06 hours on 18 Nov 1939, U-41 spotted the unescorted Darino (Master William James Ethelbert Colgan) west of Cape Ortegal and fired a torpedo on the surface at 19.02 hours, but missed. The U-boat dived after the attack, but accidentially went down to 123 metres before surfacing again and then chased the vessel for four hours. At 00.43 and 01.15 hours on 19 November, a second bow torpedo and a stern torpedo missed. At 01.50 hours, the ship was hit by the fourth torpedo and sank almost immediately. The master and 15 crew members were lost. Eleven crew members were picked up by the Germans, transferred to the Italian steam merchant Caterina Gerolimich the same day and landed at Dover.
